Complementarity between Cosmic String Gravitational Waves and long-lived particle searches in a laboratory
Satyabrata Datta, Ambar Ghosal, Anish Ghoshal +1
Cosmic strings are powerful witnesses to cosmic events including any period of early matter domination. If such a period of matter domination was catalysed by metastable, long-live…
Helicity dependent cross sections for the photoproduction of pairs from quasi-free nucleons
A2 Collaboration, D. Ghosal, V. Sokhoyan +71
Photoproduction of -pairs from quasifree nucleons bound in the deuteron has been investigated to study the helicity dependence of this reaction. Measurements with a liq…
Baryogenesis from ultralight primordial black holes and strong gravitational waves from cosmic strings
Satyabrata Datta, Ambar Ghosal, Rome Samanta
Ultralight primordial black holes (PBHs)(g) completely evaporate via Hawking radiation (HR) and produce all the particles in a given theory regardless of their other…
Predictive flavon model with mixing and baryogenesis through leptogenesis
Mainak Chakraborty, R. Krishnan, Ambar Ghosal
We use discrete group to construct a neutrino flavour model which leads to mixing and is consistent with the neutrino oscillation data. Using the model's constrained p…
A radiative Type-II seesaw model with broken Symmetry Ansatz
Satyabrata Datta, Ambar Ghosal
Parametrization of the neutrino mass matrix in terms of well-known measured quantities is an attractive way to obtain a phenomenologically viable form. We propose a model of neutri…
CP transformed mixed antisymmetry for neutrinos and its consequences
Roopam Sinha, Probir Roy, Ambar Ghosal
We propose a complex extension of mixed antisymmetry in the neutrino Majorana mass matrix . This can be implemented in the Lagrangian by a generalized CP transformation (…
